Meeting On Brucellosis

Concerns in Colorado and Nebraska have prompted Wyoming to adopt a new rule for identifying cattle from an area where they might have been exposed to brucellosis (BREW-sell-OH-sis). The Wyoming Livestock Board meanwhile has expanded the area around Yellowstone where cattle are subject to stricter testing and vaccination requirements for brucellosis, a wildlife disease that causes cows to abort their calves. Wyoming's new rule requires all sexually intact cattle that ever have been inside the disease surveillance area to carry identification disclosing that fact. Nebraska and Colorado officials worried that Wyoming required such identification only for cattle that had been in the zone as adults. The new rule applies also to calves from the zone. Public meetings on the changes are planned in Kemmerer (KEM-er-er) on Thursday and Powell on April 20.
